Questions and answers
IN FIRE HDC Speed unit will not heat above 25degrees c after starting program!
The Dentsply Sirona inFire HTC Speed unit may not heat above 25 degrees Celsius after starting the program due to several possible issues:
1. Autostart Program Issue – If the autostart program is running but the furnace does not heat up, there may be a fault in the programming or the controller board.
2. Control Panel LED Indication – If the LED on the control panel indicates heating but the furnace does not actually heat, this may suggest an issue with the heating element or the power supply.
3. Controller Board Issues – If the controller board "forgets" stored programs or time, incorrect settings may prevent proper heating.
4. Fuse or Circuit Breaker Issues – If the furnace triggers a circuit breaker, it may not be receiving sufficient power to heat beyond 25°C.
Checking the programming, ensuring the heating element is functional, and verifying the power supply can help diagnose and resolve the issue.
